Provide schema metadata in the "Meta" class

[MichalKononenko]

Marshmallow uses a nested Meta class in order to hold metadata about things like what fields to serialize. Can we use this schema to hold string fields about title, description , and $schema as defined in the JSON schema standard?

I think it does already :)

[LukeMarlin]

Where, how?

I'm quite surprised that this didn't get any reply. I've tried putting some values in Meta and it seems pretty much ignored.

Looking at the code and tests, I can see there is a way to provide a field's metadata, but not the schema metadata.

Any pointers?

[LukeMarlin]

To add a bit more to the conversation, after checking the code and tests, here is the status for some metas:

• required: generated by marking a field as required=True
• $schema: couldn't find a way to provide this
• additionalProperties: Recently added, not released yet. Simply provide additional_properties field in a Meta class under the schema

Only remaining issue for me (after the next release), would be $schema. Any reason why you don't set it automatically as "http://json-schema.org/draft-07/schema#"?

Would you accept to have a way to set it under the Meta class in a schema_uri variable for example?

Hey @LukeMarlin thanks for digging in and pulling out some of those answers.

Looking here it is setting $schema to "http://json-schema.org/draft-07/schema#".. I wonder if that's simply not in the latest version in pypi..?

[LukeMarlin]

Missed that! Given that 0.6 seems to date back to June 16, and that that line was added 22 days ago, that's probably the case.

Is it possible to release a 0.7 in the near future?

[fuhrysteve]

Just pushed 0.7.0. Hope that works for you!

[LukeMarlin]

Thank you very much, trying that at work tomorrow :)

[LukeMarlin]

Works nicely on 0.7, thanks ! :tada: OP was asking for title and description which are still missing, but that cleared my issue at least. :smiley:

Note: $id might be interesting for some users as well.

Bump - please add 'title' and 'description' support.
